1 Claim.

This invention relates to improvements in screens and has particular reference to an adjustable window screen.

ihe principal object of the invention is to provide means whereby windows of various sizes may be readily screened and at a nominal expense.

A further object is to provide a knock-down arrangement whereby an unskilled person may construct and erect a screen which is neat in appearance and which performs all the functions of an ordinary built-up screen.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. l is a front elevation of a window having my screen applied thereto,

Fig. 2 is a detail view of the expansible screen frame having a section of screen positioned thereon,

Fig. 3 is an enlarged fragmentary detail view partly in cross section showing the fanciful corner brackets,

Fig. 4 is a cross sectional view on the line 4-4 of Fig. 3, and showing a portion of screen mounted upon the frame,

Fig. 5 is a cross sectional view on the line 55 of Fig. 2,

Fig. 6 is a fragmentary detail view showing the manner in which the screen is attached to the frame, and

Fig. 7 is a fragmentary cross sectional view showing one method of securing the vertical edges of the screen.

It is customary to place screens in the windows for the purpose of excluding insects from entering the building. These screens are usually built up to the correct size to fit the windows which is an expensive procedure and if not properly done, presents an unsightly appearance. Applicant has, therefore, devised a knock-down screen arrangement which may be readily fitted to any size of window and one which will be neat in appearance, tightly stretched and easily removed when desired.

In the accompanying drawing wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numerals 5 and 6 designate top and bottom frame pieces, respectively, while the numerals 7 and 8 designate side pieces. These pieces 5, 6, 7 and 8 are preferably made of rectangular tubing split as shown at 9 (see Fig. 5). Corner brackets 11 also rectangular in cross section are of such a size as to have sliding contact with the frame pieces which they engage. The members 5 and 6 have keyhole slots 12 for the reception of hooks 13 formed upon a screen bar 14. This screen bar is made by being folded upon itself so that the end of the screen 16 may be inserted and clamped between the folded portions. A similar bar is also attached to the lower end of the screen and if desired a reinforcing bar 17 may be placed upon the screen at some intermediate point of its length. It is of course understood that the screen is cut to the proper length before the bars 14 are attached thereto.

In erecting the screen the members 5, 6, 7 and 8 are cut to substantially the proper length, after which angle members 11 are inserted as shown in Fig. 2. The frame is now placed in the window and screws placed in the members 7 and 8. The screen is now cut the proper length, the bars 14 are attached to both ends thereof and hooked into the members 5 and 6. Screws are now placed in the frame 5 and the screws are placed in the frame 6. These screws will serve to tighten the screen 16 so that the side edges thereof will lie in close contact with the side frames '7 and 8. If desired, a piece 18 may be employed to hold the side edges of the screen which piece is shown in Fig. '7. However, this piece is not necessary, particularly if the screening has a selvage edge on both of its margins.

It will thus be seen that I have produced a device which will accomplish all the results above referred to. It is of course obvious that screens may be made of standard sizes so that no cutting of the frame piece is necessary and the screen may come with the bars 14 already attached and ready for assembly.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claim:

In a device of the character described, a plurality of tubular frame members having a rectangular cross section, corner brackets slidably engaging adjacent frame members, certain of said. frame members having keyhole openings formed therein, said members being at opposite portions of said frame, and screen holding bars having hooks formed thereon and engaging in said keyhole openings.
